A single-use water filtration device comprising:

• a filter housing;
• a front housing ultrasonically welded to said filter housing;
• a filter;
• and, a first end cap and a second end cap;
• said filter non-removably contained within said first and second end caps.

A single-use water filtration device comprising:

• a filter housing;
• a front a housing affixed to said filter housing;
• a filter;
• a first end cap and a second end cap;
• said filter affixed to said first and second end caps;
• said filter and said end caps residing within said filter housing;
• said filter housing having at least one inlet and a first and second outlet for expelling filtered water;
• and, said front housing includes an adapter for connecting and disconnecting to and from, respectively, a water faucet and said front housing further includes an outlet for unfiltered water.

A water filtration device having an outlet fountain comprising:

• a filter;
• a generally cylindrically shaped filter housing having a wall defining said filter housing;
• said wall defines the interior and exterior of said filter housing and said wall includes an interior and exterior portion thereof;
• said filter housing includes an inlet and an outlet each of which extend through said wall;
• a plunger having a foot, said plunger extending through said wall of said filter housing such that said foot of said plunger resides interiorly within said wall of said filter housing;
• a valve mounted on said foot of said plunger;
• a spring operable between said exterior of said wall and said plunger urging said plunger and said foot of said plunger in a direction away from said interior of said filter housing and toward said exterior of said filter housing;
• said outlet of said filter housing includes a valve seat on said interior portion of said wall;
• and, said valve urged away from said valve seat when said plunger is depressed against the force of said spring expelling filtered water from said fountain.

A single-use faucet-mounted water filtration device comprising:

• a filter housing having an outlet for expelling filtered water therefrom;
• a front housing ultrasonically and non-removably affixed and welded to said filter housing;
• said filter housing residing rearwardly with respect to said faucet;
• a filter non-removably contained within said filter housing;
• said front housing includes an inlet and an adapter for connecting said inlet of said front housing of said water filtration device to said faucet for use of said filter and for disconnecting said water filtration device from said faucet for disposal when said filter is spent;
• said front housing includes a diverter for directing water into said filter or bypassing said filter;
• and, a gate, sensor and electronics, in combination, for measuring and indicating totalized flow through said water filtration devices.

A method of making a water filtration device comprising the steps of:
